Benefits of technology

[0007]Generally speaking, the claimed invention is a precisely guided scalpel device having a protective cover over the blade that allows a surgeon to perform a tendon sheath release procedure safely and quickly in an office. The procedure is performed through an incision about 90 to 95% smaller than a conventional incision while at the same time allowing for minimal dissection of surrounding tis

Problems solved by technology

The constant irritation from the tendon repeatedly sliding through the pulley causes the tendon to swell in this area and create the nodule.

Abstract

A device and method for minimally invasive tendon sheath release is presented herein. The device and method enables a surgeon to cut (“open”) a pulley that is obstructing a nodule and keeping a tendon from sliding smoothly. A guide probe of the device is inserted through a small incision and is used to find the edge of the pulley. Once found, the probe is guided to an end of the pulley. After proper position is assured, a hemi-cannula is moved over the guide probe to isolate the pulley from the surrounding tissue. A cutting blade is then used to sever the pulley. A dilation device may be inserted prior to the insertion of the ball tipped guide probe to dilate the area.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation in part and claims priority to currently pending U.S. patent application Ser. No. 12 / 896,088, entitled “Device and Method for Minimally Invasive Tendon Sheath Release”, filed on Oct. 1, 2010 which claims priority to U.S. Provisional Patent Application No. 61 / 251,957, entitled “DEVICE FOR MINIMALLY INVASIVE TENDON SHEATH RELEASE,” filed on Oct. 15, 2009 by the same inventor, the contents of which are hereby incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates to a novel device and method for minimally invasive tendon sheath release. More particularly, it relates to a device and method that allows a surgeon to sever a pulley that is obstructing a nodule without damaging any surrounding tissue.BACKGROUND OF THE INVENTION[0003]Tendons that move fingers are held in place on bones by a series of ligaments called pulleys (or sheath). These ligaments form an arch on a bone surface that cre...
